Videoconferencing - Resources

Many of the resources that are available on the topic of videoconferencing applications and platforms are manufacturer-specific and focused on how to support or implement their various products in your environment.  We have gathered together some of the more relevant sources of information for these products, and have also gathered links to websites that discuss or review videoconferencing solutions.

General Information and Links provides a series of links and discussions related to many internet-based technologies, including videoconferencing applications.  Their focus is primarily on consumer-grade products.  They also offer consulting services, though TTAC neither uses nor endorses these. is a forum that allows users ask questions and provide feedback to one another on the topic of videoconferencing.  They target a broad audience, including beginners and experienced technicians.  It is frequented by users, vendors, and manufacturers. and both provide a way for consumers to check the speed of their internet connection.  These can be useful tools when assessing whether or not a patient or employee working from home have sufficient bandwidth for videoconferencing applications.

Videoconferencing Test Sites

These sites provide dialing information for publicly-accessible endpoints that you can use to test your VTC system.  Additionally, one can often find links to specific addresses for testing purposes within the forum or through Google searches for “VTC Test Site.” is perhaps the most frequently referenced VTC testing system available.  Operated as an independent VTC test site, one can test the following functionality for their H.323 endpoints: connectivity, video, audio, and content. has compiled a list of 35 different SIP and H.323 test sites that is rather comprehensive in scope.  It appears to be relatively up-to-date, and the author has indicated that he intends to update the materials on an annual basis. offers a clear listing of their testing sites on this page, with a range of options for both IP and ISDN network interfaces at various bandwidths and frame rates.
